Why is it wrong for Conservatives to use racial slurs, but Liberals can call people "rednecks", "hillbillies",?

YOu also forgot they can throw fruit at Sarah Palin, make fun of her kids, and laugh about it. Did you ever hear one word from the liberal media or the liberals condemning that? I sure didn't. Have not heard one liberal on YA condemn it either. I have seen them laugh about it, make more jokes about, but one has condemned it.
